| Zusammenfassung |
| CHABLIS (Chemistry of the Antarctic Boundary Layer and
the Interface with Snow) was a collaborative UK research project aimed at
probing the detailed chemistry of the Antarctic boundary layer and the
exchange of trace gases at the snow surface. The centre-piece to CHABLIS was
the measurement campaign, conducted at the British Antarctic Survey station,
Halley, in coastal Antarctica, from January 2004 through to February 2005.
The campaign measurements covered an extremely wide range of species
allowing investigations to be carried out within the broad context of
boundary layer chemistry. Here we present an overview of the CHABLIS
campaign. We provide details of the measurement location and introduce the
Clean Air Sector Laboratory (CASLab) where the majority of the instruments
were housed. We describe the meteorological conditions experienced during
the campaign and present supporting chemical data, both of which provide a
context within which to view the campaign results. Finally we provide a
brief summary of highlights from the measurement campaign. Unexpectedly high
halogen concentrations profoundly affect the chemistry of many species at
Halley throughout the sunlit months, with a secondary role played by
emissions from the snowpack. This overarching role for halogens in coastal
Antarctic boundary layer chemistry was completely unanticipated, and the
results have led to a step-change in our thinking and understanding. |
